Currently in Brazil, some states are supplied with 127/220V voltage, such as Mato Grosso, Minas Gerais, São Paulo and Paraná, which coincidentally are among the states with the highest installed power of distributed generation (DG). The voltage values found in Brazilian territory can be consulted at this link: Voltage Levels – ABRADEE
The most common three-phase inverters sold nationwide work with a voltage of 220/380V. This happens because other countries use three-phase networks with this voltage.
Therefore, to make the output voltage levels of three-phase 220/380V inverters compatible with states with a 127/220V electrical grid, it is necessary to use transformers, which ends up making projects more expensive due to the high cost of the equipment.
The use of three-phase inverters with 127/220V output can be advantageous, especially in states that are served at this voltage level, as they do not require the use of a transformer, as the inverter output voltage will be at the same voltage level as the electrical network. – this reduces the cost and also the area used in the project.
A Figure 1 exemplifies an inverter model which has an output voltage of 127/220 V. The LV (low voltage) code signals that the inverter can connect to networks with low voltages.
In addition to having 4 MPPTs, the inverter is compatible with high power modules with 182 mm and 210 mm cells, has IP66 protection and has a maximum efficiency of 98,8%. Other characteristics can be seen in the table reproduced below, which can be found in the equipment data sheet.

Good morning
I'm going in asking for the love of God, sell me a three-phase 127/220 inverter, 15W or 17W, I already have a plant I'm just expanding, look at this for me and how I should do it.
From now on
I thank
Addison.
